摘要
露石水泥混凝土路面是一种新型路面,混凝土的耐久性是影响混凝土路面发展的关键问题。论文从抗碳化性能、抗盐冻剥蚀、耐磨性等三个方面研究露石水泥混凝土路面的耐久性。研究结果表明:露石水泥混凝土路面的碳化深度要比普通水泥混凝土路面大,表明其抗碳化性能比普通水泥混凝土差;同时露石水泥混凝土的抗冻性、抗盐剥蚀也比普通水泥混凝土路面差;但是露石水泥混凝土的耐磨性要远大于普通水泥混凝土路面。
Exposed-aggregate cement concrete pavement is a new road, the durability is the key issue of concrete pavement development. The article studies the durability of exposed-aggregate cement concrete pavement from carbon- ation resistance, salt freezing erosion, abrasion and so on. The results showed that: the carbonation depth of the ex- posed aggregate cement concrete pavement was larger than the ordinary cement concrete pavement, indicating its poor carbonation resistance; at the same time, the exposed-aggregate cement concrete pavement was poorer than the ordina- ry cement concrete pavement on frost resistance, salt erosion.But the abrasion resistance of exposed-aggregate cement concrete was much larger than the ordinary cement concrete pavement.
